Q3. Form the pair of linear equations for the following problem and find their solution by substitution method.
(ii) The larger of two supplementary angles exceeds the smaller by 18 degrees. Find them.
Let the larger angle be x and smaller angle be y
Now, As we know the sum of supplementary angles is 180. so,
Also given in the question,
Now, From (2) we have,
Substituting this value in (1)
Now, Substituting this value of x in (3), we get
Hence the two supplementary angles are
